    1. 1. Linked Data for Health Care and Life Science Research Jun Zhao University of Oxford
    2. 2. Outline <ul><li>What is Linked Data? </li></ul><ul><li>What do you need to make Linked Data? </li></ul><ul><li>What can you do with Linked Data? </li></ul>
    3. 3. EntrezGene UniProt KEGG Pathway STITCH Drugbank SIDER
    4. 4. What are the differences? <ul><li>These are not data warehouses </li></ul><ul><ul><li>Individual stores, individual SPARQL access points </li></ul></ul><ul><ul><li>Easier to maintain and to update </li></ul></ul><ul><li>They are taking advantage of the Web </li></ul><ul><ul><li>Using the web as the platform </li></ul></ul><ul><ul><li>Using URIs to identify and link entities </li></ul></ul><ul><ul><li>Building a Web-scale knowledge base </li></ul></ul>
    5. 5. How to make linked data? <ul><li>Publish data as RDF </li></ul><ul><li>Assign unique identifiers to data entities </li></ul><ul><li>Use HTTP URIs so that people can look up those names </li></ul><ul><li>Include links to other data resources so that they can discover more things </li></ul><ul><li>Provide SPARQL endpoints so that data can be accessed and queried </li></ul>
    6. 6. How….? cont. <ul><li>Linked data publication tools </li></ul><ul><ul><li>D2R server </li></ul></ul><ul><ul><li>Triplify </li></ul></ul><ul><ul><li>Pubby </li></ul></ul><ul><ul><li>Virtuoso Sponge </li></ul></ul><ul><li>Transformation scripts are widely shared and open accessible </li></ul><ul><li>Automatic link creation tools </li></ul><ul><ul><li>Silk, see presentation on Thursday 2 pm </li></ul></ul>
    7. 7. Linked Open Drug Data <ul><li>A task force of the W3C Health Care Life Science Interest Group, started since October 2008 </li></ul><ul><li>Enrich the Web of Data by publishing drug-related and as Linked Data </li></ul><ul><li>Investigate the benefits of LODD for drug discovery and biomedical research </li></ul><ul><li>~ 12 active participants, including researchers and pharmas </li></ul>
